(Alpha only) MC_SERVICES_P7 specifies whether to suppress or
    display messages about MEMORY CHANNEL activities on this node.
    This parameter can be set to a value of 0, 1, or 2:

    o  A value of 0 indicates nonverbose mode: no informational
       messages appear on the console or in the error log.

    o  A value of 1 indicates verbose mode: informational messages
       from both MCDRIVER and PMDRIVER appear on the console and in
       the error log.

    o  A value of 2 provides the same output as a value of 1, with
       the addition of PMDRIVER stalling and recovery messages.

    The default value is 0. HP recommends that this value not
    be changed except while debugging MEMORY CHANNEL problems or
    adjusting the MC_SERVICES_P9 parameter.

    MC_SERVICES_P7 is a DYNAMIC parameter.
